6.186

《論》：「世俗有三。」皆持業釋，由此二空，能顯了真，非即真如，故名世俗。或取所顯，帶相觀真，未是親證，望廢詮證，故名顯了，亦持業釋。

The Śāstra states: "Conventional [truth] has three [forms]." All of these are appositional compounds (karmadhāraya). Because these two empties can reveal and clarify the true, yet are not identical with tathatā, they are called conventional. Or, taking what is revealed: contemplating the true while carrying an image (ākāra) is not yet direct realization; relative to realization that abandons verbal expression, it is called "revelatory," and this is also an appositional compound.
